Specification of application ated January le, wie.

To all whom t may concertar Be it known that l, Winners W. lnnnnn.;

a citizen of the United States, and resi den-t of Charleston, in the conntyoli Charles ton and State of South Carolina, have invented nev'v and useful lrnprovements in Car-Wheels, of which the following' is a specification. n

rlhis invention relates to car Wheels and has particular' reference to that class et ear Wheels employing a supplemental rim or tread. l

An important object of the invention is to provide in a device of the above mentioned character a means whereby the supplemental rim may be easily placed upon the wheel and securely locked in position thereupon.

A further objectl of the invention is to provide in a device of the above mentioned character a means whereby the riin may he 'readily unlocked and quickly removed or detached from the Wheel.

A farther object of the invention is to provide in a device of the above mentioned character a locking mechanism 'for the suplemental rim or tread which under varylng conditions may be maintained at all times in a locked position.

A further object of the invention is to -provide a `device of the. above mentioned character which is simple in construction, cheap to manufacture, strong7 durable, and reliable in operation.

Other objects and advantages of the invention will be apparent from the tollonf'ing description. j

In the drawings forming a part or' this Specification and in which like numerals are employed to designate like parts throughout the same,

Figure 1 is a fragmental view showing in elevation a portion of the device embodying my invention,

taken on the line 2-2, and,

, Fig. 3 is a cross sectional view ot a car VWheel embodying va modified form of the l. invention Y In the drawings the numeral 5 indicates the. main body ola car Wheel provided rela- ,ltively near its periphery with a flange 6 die g (posed at substantially a right-angle to the jf main body of the car Wheel 5 as shown.

The: main body 5 of the car Wheel is prou vided also with an npstanding tlange l Fig. 2 isa/cross sectional View oli Fig. 1

ing a plurality olf transversely disposed openings tl provided therein. llhis npstanding flange i' is slightly enlarged as shown at S, relatively near its peripheral edge and is provided 'with an inclined face l0. rlfhe foregoing is common to `both iforms oi my invention.

Upon the inclined face l0 'there is disposed a supplemental rim il provided relatively ncer one edge tlnireof` tvitlran inclined tace l2 adapted, to engage the`inclined tace l0 as shown. 'lhis supplemental rim or tread carries an enlarged portion 13 forming a llange similar to that employed in the conventional torni of car wheel structure. in annular lelis carried between the llange (l and the supplemental rim or tread lil and is provided at one edge thereof with a ilange l5 adapted to yengage the liange 6 as shown, while the other edge is orovided with a flange l@ having a beveled 'face ll" adapted to engage an inner beveled face l@ carried by the supplemental rim ll shown. A bolt 19 is passed through lthe opening 8 provided by the opstanding tlange 7 and an opening 20 provided by the annular ring le and is held in position as shown by means of a nut 21 carried thereby and engaging the outer `face of the annular ring le. As the means for locking the nut 21 in position with respect to the bolt 19 there is provided a second nut 22 carried by the bolt i9 and adapted to engage the nut 2l as shown. 1

lln considering llig. 3 wherein is shown a modified Jforno of my invention, the numoral Q3 indicates a supplemental rim or tread identical With that indicated by 'the numeral ll shown in lli 2 except, however. l have provided a depending dange 2liprovided with a plurality oli openings 25 adapted to receive 'the bolts 19. This depending 'llange Ell `is held in engagement with the upstanding flange 'l by means of a nut 26 'carried by the bolt 19 and engaging the the nuts 21 and 22 serve as a means 'for retaining the annular ring 14C in the position shownw. It is to be understood that as the nut 2l is run down upon the screw threaded bolt 19 the annular ring 14 is carried in the direction of travel of the same whereupon the inclined face 17 of the annular ring 14: oo-aets With the inclined face 18 of the tread ll thereby gradually tightening the rim or tread 111,.y in the position desired. it will be furthen understood that the ring le serves not only as a means for retaining the supplemental rini or tread 11 in position but as a ineans whereby any Wear or loosening between the supplemental rim or tread ll and the annular ring 14C may be compensated.

The assembling of' the Inodified form oi' my invention is substantially the same as that of the preferred form which'has been hereinbefore described and which will be re dily understood after having considered tll specification together with the disclosure relative to the preferred form of my invention.

It is to be understood that various changes in the shape, size and arrangement of parts may be resorted to without departinglfroin the spirit of my invention or the scope of the subjoined olaiin.

Having thus described my invention, what I claim, as new and desire to secure and pro-i i ,eene-ir teet by Letters Patent oi the "United States, is:

A device of the character described poinprising a main body provided With a flange disposed substantially at right angles thereA to, a second flange carried by the main body and provided with an enlarged head having an inclined face, an annular ring dis posed upon the first mentioned Harige said annular ring comprising a pair o' oppositely disposed flanges, one ot said flanges having engagement with the first mentioned fiange, the other of said fianges being provided with an inclined face, a supplemental rim disposed upon the second mentioned iiange and provided with ineiined faces one oi' which is adapted to engage the ineiined.

Linee carried by the second named flange the einer oi which is adapted to engage the inclined face carried by the annular ring, ay depending iange secured to said Sappienientai riin, said depending Hange being winined between 'the second named flange and said annular ring bolt passed through said annular ring, said depending tlange .-.nd the second. nanied iiange, said boitl be ing adapted to retain the annuiar ring in engagement with the first mentioned dangle and the sup;` ieiuentai rin` and means tor retaining sai Harige in e" 'agement with the second naar l iiange..
